What OS X version are you on? Yes, today 02-04 is the same, and I am using OSX 10.5.6. I am sorry but I am unable to reproduce it in other simple setup. However, we seem to trace down that the issue is about regular expression matching, as also mention in: http://lists.gnu.org/archive/html/emacs-devel/2009-02/msg00012.html, there are some clue about function "re-search-forward" I profile in my w3m case, with exactly the same procedure here comes: Function Name Call Count Elapsed Time Average Time ====================== with 2009-02-04 Emacs executable ======================= regexp-opt-group 2668 2.5593199999 0.0009592653 re-search-forward 730 1.4294740000 0.0019581835 run-hooks 38 1.3881749999 0.0365309210 regexp-opt 162 0.8015100000 0.0049475925 regexp-quote 1650 0.0171659999 1.040...e-05 remove-text-properties 506 0.0074000000 1.462...e-05 ====================== with 2009-01-19 Emacs executable ======================= regexp-opt-group 2668 0.4568619999 0.0001712376 regexp-opt 162 0.1268280000 0.0007828888 re-search-forward 730 0.0308000000 4.219...e-05 run-hooks 37 0.029099 0.0007864594 run-at-time 41 0.0009150000 2.231...e-05 regexp-quote 1650 0.0008870000 5.375...e-07 remove-text-properties 506 0.0007210000 1.424...e-06 Is there any specific changes in regular expression part in 2009-01-30 (not about lisp but the Emacs executable)? > > thanks. ^ permalink raw reply [flat|nested] 6+ messages in thread

There were no OS X-specific changes in the RE area, and it sounds like other platforms are experiencing similar issues. ^ permalink raw reply [flat|nested] 6+ messages in thread
